Completely disposable cooking apparatus for filling and decorating of foods

ABSTRACT

A cooking apparatus used for filling and decorating of foods, comprising in some embodiments a one-piece, funnel-shaped bag with a soft side wall, having an open first end at the “top” through which food material and coloring agents can be inserted into the bag and a closed second end at the “bottom” end of the funnel, with an integral, malleable, conical shaped, discharge orifice. The orifice may have serrations or ridges extending inwardly from the internal wall of the orifice, running longitudinally or parallel to the cone axis. The orifice may be initially closed or manufactured with a small opening. The orifice may be made of a material capable of being cut to yield an exit opening. The inwardly extending serrations that remain after a cut may insure that the material is “treated” as it is expelled from the bag through the orifice to yield a ribbon candy design.

No. 13/366,863, filed Feb. 6, 2012 (issued on Jul. 29, 2015 as U.S. Pat. No. 8,790,110), which is a continuation-in-part of U.S. patent application Ser. No. 13/184,021, filed Jul. 15, 2011 (issued on Aug. 5, 2014 as U.S. Pat. No. 8,794,959). The entire disclosures of those applications are hereby incorporated herein by reference.

BACKGROUND OF THE INVENTION

The EASY FILL BAG™ (“EFB”) apparatus of this invention “resembles” a commonly used, prior art “Disposable Decorating Bag” (“DDB”), such as those manufactured and sold by Wilton Brands, Inc., Hutzler Manufacturing Co., Inc. and Kitchen Krafts, Inc.

However, there are significant differences between the EFB apparatus of this invention and the previous DDB apparatus, both in terms of construction and manner of operation.

The typical DDB apparatus is a multi-piece construction, including a bag, a non-disposable rigid decorating tip with treatment means at the annular discharge end of the tip and a coupler and coupler collar. Typical DDB tips are made of metal or rigid white plastic and the coupler and coupler collar are made of rigid white plastic.

In order to use the DDB apparatus, a DDB bag is assembled with a desired decorating tip (i.e., with the desired opening size and treatment means at the annular end) using a coupler and coupler collar.

The ability to have different sized discharge openings with a DDB apparatus necessitates the user having a selection of different tips.

If, after initial use, the user decides a larger size opening is desired, the user must disassemble the DDB apparatus and reassemble the DDB apparatus with a new tip.

If the user wants to create an output with a three dimensional ribbon candy design, i.e., a stream of food material with channels having alternating stripes of color on the channel peaks and in the channel valleys, it is not possible with the DDB apparatus.

During use of the DDB apparatus, if the selected tip becomes “clogged,” i.e., if the material being expelled out of the DDB apparatus through the tip has a “lump” that gets “stuck” in the tip, the bag and tip must be disassembled so that the tip can be accessed and cleaned.

Once use of the DDB apparatus is completed, the DDB apparatus is taken apart, the bag is disposed of, and the tip, coupler and coupler collar are cleaned and stored away for future use.

The EFB apparatus of this invention, on the other hand, in the preferred embodiment, is a one-piece, fully disposable construction, comprising a funnel-shaped bag with an integral, flexible, conical shaped discharge orifice at the end for “treating” material being expelled from the bag through the end. The discharge orifice has protrusions, serrations or ridges extending inwardly from the internal wall of the orifice and running longitudinally or parallel to the conical axis, along all or a part of the length of the discharge orifice. The orifice is made of a material so that it is capable of being cut at any point along its longitudinal dimension or along its conical axis to yield an exit opening or hole with a desired size or cross-sectional dimension. Regardless of the point of cut, i.e., regardless of the size of the hole or opening or the cross-sectional dimension, the inwardly extending serrations or ridges that remain insure that the material is “treated” as it is expelled from the bag through the orifice to yield a three dimensional ribbon candy design, i.e., a stream of food material with channels having alternating stripes of color on the channel peaks and in the channel valleys. While the orifice at the end of an EFB apparatus is capable of “treating” the material as it is discharged from the bag, the orifice is also either: (a) elastic or flexible enough in order to allow the hole or opening in the orifice to expand to pass “clogs” or “lumps” and then return to its original shape; or (b) supple or deformable enough in order to allow the orifice to be compressed or collapsed “upstream” of the hole or opening so that the “clogs” or “lumps” can be broken up and then passed through the hole or opening when the orifice returns to its original shape.

In an alternative embodiment, the EFB apparatus of this invention has sections of the orifice with protrusions, serrations or ridges extending inwardly from the internal wall of the orifice and running longitudinally or parallel to the conical axis and longitudinal sections without protrusions, serrations or ridges so that the orifice can be cut at one of those areas and used as a piping bag.

In the absence of the availability of EFB apparatus as disclosed herein, individuals have been known to take readily available ZIPLOC® and GLAD® zipper plastic bags, fill them with food material and cut the corner of the bag in order to create “homemade” disposable decorating bags with a “dispensing hole.” Such “homemade” bags are unsatisfactory for several reasons, most notably because: (i) they do not permit the “treatment” of the material as it exits the “hole”; (ii) the lack of an orifice prevents the desired controlled delivery of the food material; and (iii) there are inadequate means for dealing with lumps in the food material and the forced passage of the lumps out of the bag typically causes the opening of the bag to permanently widen, such that thereafter the food material is dispensed at an undesirable flow rate or worse, for the bag to no longer function.

SUMMARY OF THE INVENTION

The EASY FILL BAG™ (“EFB”) apparatus of this invention in a preferred embodiment is a one-piece disposable construction, comprising a funnel-shaped bag with a soft side wall, having an open first end at the “top” or wider end of the funnel through which food material and coloring agents can be inserted into the bag and a closed second end at the “bottom” or narrow end of the funnel, with an integral, malleable, conical shaped, discharge orifice. The conical shaped orifice has protrusions, serrations or ridges extending inwardly from the internal wall of the orifice and running longitudinally or parallel to the conical axis, along all or a part of the length of the conical shaped orifice. The orifice can either be initially closed or provided with a small opening or hole. The orifice is made of a material so that it is capable of being cut at any point along its longitudinal axis to yield an exit opening or hole with a desired size or cross-sectional dimension. Regardless of the point of cut, i.e., regardless of the size of the hole or opening or cross-sectional dimension, in the preferred embodiment, the inwardly extending serrations or ridges that remain insure that the material is “treated” as it is expelled from the bag through the orifice to yield a three dimensional ribbon candy design, i.e., a stream of food material with channels having alternating stripes of color on the channel peaks and in the channel valleys. While the orifice at the end of an EFB apparatus is capable of “treating” the material as it is discharged from the bag, the orifice is also either: (a) elastic or flexible enough in order to: (a)(i) allow the orifice to “open up” or “expand” so that “clogs” or “lumps” can pass through the orifice while still “treating” the material being passed therethrough; and (a)(ii) cause the orifice to return to its original shape after the “clog” or “lump” has passed in order to continue to “treat” material that subsequently passes through the orifice; or (b) supple or deformable enough in order to: (b)(i) allow the orifice to be compressed or collapsed so that the “clogs” or “lumps” can be broken up so that they can pass through the orifice; and (b)(ii) cause the orifice to return to its original shape after the “clog” or “lump” has been broken up in order to “treat” all of the material that passes through the orifice.

In one embodiment, the bag side wall is made of a temperature impervious material, which allows the user to work with a variety of materials, including very warm and very cold materials.

In another embodiment the bag side wall has texturing to facilitate gripping by the user.

In an alternative embodiment, the EFB orifice of this invention is provided without being attached to an integral bag, but rather, with a mating collar, and the EFB orifice is affixed to a bag in the manner of a traditional DDB apparatus, such that the benefits and features of this invention are achieved albeit at a slightly higher price and without the convenience of the integral one-piece completely disposable design.

In still a further embodiment, the EFB apparatus is used in combination with a stand that engages and supports the EFB apparatus during filling. More particularly, the EFB apparatus can be supported by mating mechanisms on the EFB apparatus and the stand, e.g., three “support holes” along the “top” of the EFB apparatus that “attach” to fingers of the EFB stand, or an excess of EFB side wall material that is reversible on itself for folding over arms of the EFB support stand. Using the EFB stand allows the user to fill the bag easily with both hands free.

The EFB apparatus of this invention can be used for piping, decorating, filling, assembling and dispensing the food material in connection with any number of other cooking and baking activities without departing from the scope of this invention, e.g., cakes and cupcakes, stuffed shells, manicotti, cannoli's, deviled eggs, stuffed mushrooms, twice baked potatoes, cookies, canapes, pastry cups, meringue, etc.

The EFB apparatus comes in a variety of sizes, with “larger” EFB apparatus having larger bags and comparatively larger orifices.

The EFB apparatus is completely disposable once use of it is complete.

The EFB apparatus of this invention will be packaged and sold like reusable, re-sealable zipper storage bags, such as the ZipLock® bags originally developed by Dow Chemical Company and now produced by S. C. Johnson & Son or Glad® bags produced by The Glad Products Company.

Each box (or each “starter box”) of the EFB apparatus of this invention may include an apparatus stand, which will enable the user to attach each of the EFB apparatus in the box upright on the stand for ease of filling.

An object of the disclosed invention is to provide individuals with bags that have an integral unique discharge orifice (also sometimes referred to as a nozzle or a tip) that can be used to dispense treated food material and then completely disposed of.

A further object of the disclosed invention is to provide individuals with bags, the universal orifice of which can be cut to a desired hole or opening size, while still retaining the treatment capacity of the orifice.

A further object of the disclosed invention is to provide individuals with bags, the orifice of which is made of a malleable material such that “clogs” or “lumps” do not clog the orifice.

A still further object of the disclosed invention is to provide individuals with bags, the orifice of which is made of a sufficiently elastic material so that the orifice can expand to allow “clogs” or “lumps” to pass through the orifice and the orifice can then return to its original shape.

A still further object of the disclosed invention is to provide individuals with bags, the orifice of which is made of a sufficiently deformable material so that the orifice can be collapsed to break up “clogs” or “lumps” so that they can pass through the orifice and the orifice can return to its original shape.

A still further object of the disclosed invention is to provide individuals with bags, the orifices of which have a star-shaped cross section along its longitudinal length.

A still further object of the disclosed invention is to provide individuals with bags, the orifices of which have cutting guides that can be indicated by scoring or coloring applied to the outside wall of the orifice and corresponding to a preset orifice hole or exit opening size.

A still further object of the disclosed invention is to provide individuals with bags with universal orifices, so that the bags can be interchangeably used both for dispensing food material that has been “treated” with a design and for dispensing food material that can be used for “piping.”

A still further object of the disclosed invention is to provide individuals with bags, inside of which color delivery means allows color to be added to the food material as it is forced out of the EFB apparatus.

A yet further object of the disclosed invention is to provide individuals with bags, the nozzle of which is made out of material with a durometer of between 27 A and 60 A.

A yet further object of the disclosed invention is to provide individuals with bags, the orifice of which is made out of a material that is elastic, such as a thermoset elastomer, such as latex rubber or silicone rubber, or a thermoplastic elastomer, such as polyurethane.

A yet further object of the disclosed invention is to provide individuals with bags, the orifice of which is made out of a material that is flexible, but not elastic, such as a thermoplastic such as polyethylene.

A yet further object of the disclosed invention is to provide individuals with bags, where the orifice can be cut to afford a bag opening with an internal diameter of up to 0.8 inches.

A yet further object of the disclosed invention is to provide individuals with bags, the soft side of which is made from polyethylene that can be welded to the orifice material.

A yet further object of this invention is to provide individuals with universal orifices and mating clamping mechanisms, that can be used with traditional bags, which orifices can be both cut to a desired hole or opening size while still retaining the treatment capacity of the orifice, or cut to a different desired hole or opening size for piping purposes, and where such orifice is made of a malleable material such that “clogs” or “lumps” do not clog the orifice.

A still further object of this invention is to provide a conical shaped orifice which has protrusions, serrations or ridges extending inwardly from the internal wall of the orifice and running longitudinally or parallel to the conical axis, along the length of the conical shaped orifice, such that regardless of where the orifice is cut and regardless of the resultant size of the hole or opening or cross-sectional dimension, the inwardly extending protrusions, serrations or ridges that remain insure that the food material that has been exposed to coloring agents that were applied to the inside of the bag is “treated” as it is expelled from the bag through the orifice, more particularly, the protrusions, serrations or ridges cut into the food material, causing the food material to split into alternating stripes of food material that: (a) has been in contact with the coloring agents on the inside of the bag and displays the effects of the coloring agents on the food material as it is expelled out through the orifice; and (b) has not been in contact with the coloring agents on the inside of the bag and passes out through the orifice without displaying any effect from the coloring agents.

A still further object of this invention is to provide a conical shaped orifice which has protrusions, serrations or ridges extending inwardly from the internal wall of the orifice and running longitudinally or parallel to the conical axis, along the length of the conical shaped orifice, such that the user can create an output with a three dimensional ribbon candy design, i.e., a stream of food material with channels having alternating stripes of color on the channel peaks and channel valleys, both initially when the orifice is cut for a small size output, and subsequently when, without the muss and fuss of disassembly, the orifice is simply cut for a larger size output.

DETAILED DESCRIPTION OF THE INVENTION

The EASY FILL BAG™ (“EFB”) apparatus of this invention can be used with a variety of viscous foodstuffs, including to assemble, fill and prepare a variety of foods, such as stuffed shells, manicotti, cannoli's, deviled eggs, stuffed mushrooms, 2× baked potatoes, cookies, canapes, pastry cups, meringue, etc., and to decorate with icing and the like.

In a preferred embodiment, the EFB apparatus is a completely disposable, one-piece construction, comprising a bag with an integral, flexible discharge orifice at the end for “treating” material being expelled from the bag through the end.

To create an aesthetic design in the dispensed material, the EFB apparatus includes an integral orifice in the end that has jagged inwardly facing edges or protrusions, ridges or serrations that “treat” the material as it passes through the orifice.

While the orifice at the end of an EFB apparatus is capable of “decorating” the material as it is discharged from the bag, the orifice is also flexible or supple enough in order to: (i) allow the orifice to “open up” or “expand” so that “clogs” or “lumps” can pass through the orifice; and (ii) cause the orifice to return to its original shape after the “clog” or “lump” has passed in order to “treat” material that subsequently passes through the orifice.

The EFB bag can be made of a material that inhibits the transfer of heat or cold from the contents of the bag through to the user's hands.

The EFB bag can be made with a textured exterior surface so as to facilitate the user's gripping of the EFB bag.

Once use of the EFB apparatus is completed, it is the intention of this invention that the entire one-piece EFB apparatus is disposed of.

The EFB apparatus comes in several sizes, with larger EFB apparatus having larger bags and respectively larger integral, flexible discharge orifices.

The EFB apparatus comes with a stand that engages and supports the EFB bag during filling. More particularly, the EFB apparatus can be supported by mating mechanisms on the EFB bag and the stand, e.g., “support holes” in the EFB bag that “attach” to fingers of the EFB stand, or an excess of EFB bag material that is reversible on itself for folding over arms of the EFB support stand.

EFB apparatus will be packaged and sold like reusable, re-sealable zipper storage bags, such as the ZipLock® bags originally developed by Dow Chemical Company and now produced by S. C. Johnson & Son, or the Glad® bags sold by The Glad Products Company.

It is envisioned that a “starter” box of EFB apparatus, or possibly every box of EFB apparatus, may include an apparatus stand, which will enable the user to attach each EFB bags upright on the stand for ease of filling.

In the preferred embodiment, the EFB apparatus includes a funnel shaped bag for easy filling, handling, decorative dispensing, and disposing.

The choice of discharge orifice (or nozzle) material may be driven to some extent by the target cost of the product. Whatever the material is, it must enable the user to clear clogs without taking the food out of the bag, either by expanding to allow the clog to pass (preferred) or allowing the user to crush and break up the clog (preferred and alternate).

In an alternative embodiment, the discharge orifices (or nozzles) of the EFB apparatus are sold separately, i.e., without an attached bag, but rather, with a mating connection mechanism, such as a collar, so that the EFB orifice and mating connection mechanism can be attached to a traditional bag of any size.

Referring now to the figures, FIGS. 1 through 4 show a first, preferred embodiment of an EFB apparatus in accordance with this invention.

In FIG. 1, a side view of the nozzle or discharge orifice 10 is shown, with an integral bag 12. The bag 12 is funnel shaped and the bag 12 is either attached to the nozzle 10 during manufacture, as a simultaneously created one piece construction, or the bag 12 is attached to the nozzle 10 in a secondary operation, e.g., by making the nozzle first, for example, by injection molding, and then by dip molding the bag over it, or by welding, gluing or connecting the nozzle and bag together by other means available and known in the art, including by using a disposable connection mechanism. The bag 12 has a first end 14 that is at the “top” or wider end of the funnel shape that is “open” and through which the food material 10A can be inserted into the bag 12, a second end 16 that is at the “bottom” or narrow end of the funnel shape that is “closed” as a result of the attachment of the nozzle 10, and a soft side wall 17 that allows the user to squeeze the bag 12 and cause food material 10A in the bag 12 to be expelled out of the bag 12 through the nozzle 10. The nozzle 10 is malleable and conical shaped and has a conical axis 18 and a discharge opening or hole 20. The sections 10 a, 10 b, 10 c and 10 d of the nozzle 10 are increasingly larger in cross-section and each respectively has a “cut line” 21 a, 21 b, 21 c and 21 d at which the nozzle 10 can be cut prior to or during use to achieve different the desired different opening or hole 20.

FIG. 2 shows a cut away view of the nozzle 10 of FIG. 1, taken along the line 30-30 in FIG. 1. The elements of the nozzle 10 seen in FIG. 1 that are still visible in FIG. 2 are similarly numbered. FIG. 2 additionally shows the internal wall 32 of the nozzle 10 and the protrusion, serrations or ridges 34 that extend inwardly from said internal wall 32 and run longitudinally along the length of the nozzle 10, parallel to the conical axis 18. Thus it can be seen that regardless of whether the nozzle 10 is cut at “cut line” 21 a, i.e., at a point close to the hole 20 and before the protrusions 34 begin, or at any of the other “cut lines” 21 b, 21 c or 21 d, which would cause a portion of the protrusions 34 also to be cut, lengths of the protrusions 34 remain within the nozzle 10 that “treat” the food material 10A as it passes from the bag 12 through the nozzle 10 and out the hole 20.

FIG. 3 is a top view of the nozzle 10 (as would be seen were one to look at the nozzle down into and through the bag 12). The protrusions 34 extending inwardly from the internal wall 32 create a star-shape that is imparted to the food material 10A as it passes through the nozzle 10 and is “treated” thereby.

FIG. 4 is a bottom view of the nozzle 10 before any cut has been made, showing all of the sections 10 a, 10 b, 10 c and 10 d and the cut lines 21 a, 21 b, 21 c and 21 d.

Either before or after the food material 10A is introduced into the bag 12, the user cuts the nozzle 10 at a desired cut line 21 a, 21 b, 21 c or 21 d to achieve a desired opening or hole 20 and controlled dispensation of the food material 10A out through the nozzle 10. If the user initially cuts at cut line 21 b, sufficient length of protrusions 34 remain to “treat” the food material 10A as it passes through the nozzle 10. If a lump clogs the nozzle 10, the nozzle is malleable enough to allow the lump to “pass.” The manner in which the nozzle 10 will “pass” the lump depends upon which of the two embodiments of the invention is being employed. If the nozzle 10 is elastic, it will expand upon the user's application of pressure to the bag 12 and the lump will be expelled and the nozzle 10 will return to its normal size and shape. Alternatively, if the nozzle 10 is plastic, it will allow the user to apply pressure to the lump upstream of the opening 20 by squeezing the nozzle, to thereby break up the lump. The broken up lump will then be able to pass through the opening 20 and the nozzle will return to its normal size and shape.

During use, if the user would like to increase the size of the opening or hole 20, the user can elect to make a further cut in the nozzle 10. For example, if the user made the first cut at line 21 b as described above, the user can elect to make a further or second cut in the nozzle 10 at cut line 21 c or at cut line 21 d to achieve a desired larger opening or hole 20 and controlled dispensation of a greater amount of the food material 10A out through the nozzle 10. If the user cuts at cut line 21 c or cut line 21 d, sufficient length of protrusions 34 nevertheless still remains to “treat” the food material 10A as it passes through the nozzle 10. If a lump clogs the nozzle 10, the nozzle is still malleable enough to allow the lump to “pass.” The manner in which the nozzle 10 will “pass” the lump still depends upon which of the two embodiments of the invention is being employed. If the nozzle 10 is elastic, it will still expand upon the user's application of pressure to the bag 12 and the lump will be expelled and the nozzle 10 will return to its normal size and shape. Alternatively, if the nozzle 10 is plastic, it will still allow the user to apply pressure to the lump upstream of the opening 20 by squeezing the nozzle, to thereby break up the lump. The broken up lump will then be able to pass through the opening 20 and the nozzle will return to its normal size and shape.

If the user needs to, additional material can be added to the bag 12. Once the user is finished, the entire EFB apparatus can be completely disposed of.

FIGS. 1-4 show a preferred embodiment of the EFB apparatus according to this invention where the protrusions 34 run the length of the nozzle 10. FIGS. 5-8 show an alternative embodiment where the protrusions 36 are sections strategically placed between the cut lines.

In FIG. 5, a side view of an alternative nozzle or discharge orifice 110 is shown, with an integral bag 112. The bag 112 is funnel shaped and the bag 112 is either attached to the nozzle 110 during manufacture, as a simultaneously created one piece construction, or the bag 112 is attached to the nozzle 110 in a secondary operation, e.g., by making the nozzle first, for example, by injection molding, and then by dip molding the bag over it, or by welding, gluing or connecting the nozzle and bag together by other means available and known in the art, including by using a disposable connection mechanism. The bag 112 has a first end 114 that is at the “top” or wider end of the funnel shape that is “open” and through which the food material 10A can be inserted into the bag 112, a second end 116 that is at the “bottom” or narrow end of the funnel shape that is “closed” as a result of the attachment of the nozzle 110, and a soft side wall 117 that allows the user to squeeze the bag 112 and cause food material 10A in the bag 112 to be expelled out of the bag 112 through the nozzle 110. The nozzle 110 is malleable and conical shaped and has a conical axis 118 and a discharge opening or hole 120. The sections 110 a, 110 b, 110 c and 110 d of the nozzle 110 are increasingly larger in cross-section and each respectively has a “cut line” 121 a, 121 b, 121 c and 121 d at which the nozzle 110 can be cut prior to or during use to achieve different the desired different opening or hole 120.

The difference between the nozzle 10 and nozzle 110 is that, as best seen in FIG. 6 (a cut away view of the nozzle 110 of FIG. 5, taken along the line 40-40 in FIG. 5), depending upon where the cut is made in the nozzle 110, the opening 120 will end up being either an annular opening without protrusions 110 (i.e., if the cut is made at 121 a or 121 c) or an opening with the inwardly extending protrusions 134 a (if the cut is made at 121 d) or protrusions 134 b (if the cut is made at 121 b). The elements of the nozzle 110 seen in FIG. 5 that are still visible in FIG. 6 are similarly numbered. FIG. 6 additionally shows the internal wall 132 of the nozzle 110 and the protrusion, serrations or ridges 134 a and 134 b that extend inwardly from the internal wall 132 and run longitudinally for discrete sections along the length of the nozzle 110, parallel to the conical axis 118.

FIG. 7 is a top view of the nozzle 110 (as would be seen were one to look at the nozzle 110 down into and through the bag 112). The protrusions 134 a and 134 b extending inwardly from the internal wall 132 create two different star-shapes, one of which might be imparted to the food material 10A as it passes through the nozzle 110, depending upon the cut that is made in the nozzle 110, as described herein.

FIG. 8 is a bottom view of the nozzle 110 before any cut has been made, showing all of the sections 110 a, 110 b, 110 c and 110 d and the cut lines 121 a, 121 b, 121 c and 121 d.

As with the preferred embodiment, either before or after the food material 10A is introduced into the bag 112, the user cuts the nozzle 110 at a desired cut line 121 a, 121 b, 121 c or 121 d to achieve a desired opening or hole 120 and controlled dispensation of the food material 10A out through the nozzle 110. If the user initially cuts at cut line 121 a or 121 c, the food material 10A will pass through the resultant annular opening without any sort of design “treatment.” If the user cuts the nozzle 110 at 121 b or 121 d, the protrusions 134 b and 134 a, respectively, will “treat” the food material 10A as it passes through the nozzle 110.

Regardless of where the cut in the nozzle 110 is made, if a lump clogs the nozzle 110, the nozzle is malleable enough to allow the lump to “pass.” The manner in which the nozzle 110 will “pass” once again depends upon which of the two embodiments of the invention is being employed. If the nozzle 110 is elastic, it will expand upon the user's application of pressure to the bag 112 and the lump will be expelled and the nozzle 110 will return to its normal size and shape. Alternatively, if the nozzle 110 is plastic, it will allow the user to apply pressure to the lump upstream of the opening 120 by squeezing the nozzle, to thereby break up the lump. The broken up lump will then be able to pass through the opening 120 and the nozzle will return to its normal size and shape.

During use of the alternative embodiment of FIGS. 5-8, if the user cuts the nozzle 110 at cut line 121 b, the food material 10A will be “treated” by protrusions 134 b as it is passed through the nozzle 110 and out of the opening 120. If the user would like to switch and have the food material 10A dispensed without treatment, e.g., for “piping,” the user can elect to make a further or second cut at cut line 121 c. Thereafter, the user can elect to make a still further or third cut in the nozzle 110 at cut line 121 d so that the food material 10A will be “treated” by protrusions 134 a as it is passed through the nozzle 110 and out of the opening or hole 120.

Regardless of where the user cuts the nozzle 110, if a lump clogs the nozzle 110, the nozzle 110 is still malleable enough to allow the lump to “pass.” The manner in which the nozzle 110 will “pass” the lump still depends upon which of the two embodiments of the invention is being employed. If the nozzle 110 is elastic, it will still expand upon the user's application of pressure to the bag 112 and the lump will be expelled and the nozzle 110 will return to its normal size and shape. Alternatively, if the nozzle 110 is plastic, it will still allow the user to apply pressure to the lump upstream of the opening 120 by squeezing the nozzle 110, to thereby break up the lump. The broken up lump will then be able to pass through the opening 20 and the nozzle 110 will return to its normal size and shape.

The user can refill the bag 112 of the apparatus of alternate embodiment as needed and, once the user is finished, the entire EFB apparatus can be completely disposed of.

FIG. 9 shows a bottom view of a nozzle 210 according to this invention with a design for protrusions 234 extending inwardly from the inside wall 232 that has been found to be preferred.

FIG. 10 shows a nozzle 310 attached to bag 312, for dispensing food material 10A, which nozzle 310 is similar to the nozzle 110 shown in FIGS. 5-8, in that it has alternating internal profiles. The internal profiles of sections 310 a, 310 b and 310 c are circular and the internal profiles of sections 310 d and 310 e are star shaped as a result of the internal protrusions 314 a and 314 b. Where the cut is made in nozzle 310 will alter the manner in which food material 10A is dispensed out of hole 320.

FIG. 10A shows a nozzle 320 attached to the bag 322, for dispensing food material 10A, which nozzle is similar to the nozzle 310 shown in FIG. 10 and the nozzle 110 shown in FIGS. 5-8, in that it has alternating internal profiles. The internal profiles of sections 320 a, 320 b and 320 c are all circular and they all are of the same cross-sectional dimension. The internal profiles 320 d and 320 e have identically sized internal protrusions 324 a and 324 b and they are of the same cross-sectional dimension. Accordingly, during use, the user can select to make a cut at 320 a for “un-treated” dispensing of the food material, and then to make a cut at 320 d for effecting “treated” dispensing of the food material, and then another cut at 320 b for the same “un-treated” dispensing as effected by section 320 a, and then a cut at 320 e for the same “treated” dispensing as affected by section 320 d, and finally a cut at 320 c for effecting the same “un-treated” dispensing as effected by sections 310 a and 310 b.

FIG. 11 shows a multiple outlet device with nozzles 410, 510 and 610 in accordance with this invention.

FIGS. 12-26 disclose various stands for use with the EFB apparatus during filling with food material.

The stand shown in FIGS. 12-16 is a wire stand 910, shown with a base ring 911 and four extending support arms 912 a, 912 b, 912 c and 912 d. Each support arm has a support finger 914 a, 914 b, 914 c and 914 d for engaging (as shown in FIG. 16) corresponding to holes 920 a, 920 b, 920 c (920 d not shown) in the bag 990.

The stand 344 shown in FIGS. 17-22 is a collapsible annular stand with a number of nesting sections 350 a, 350 b, 350 c, 350 d and 350 e and a base 325. Stand 344 engages and supports the EFB bag during filling by having an excess amount of EFB bag material that is reversible on itself folded over the top edge 352 of section 350 a. The stand 344 is “opened” by the user by pulling apart the outer nesting section 350 a and the base 352. The stand remains “open” by friction or other means as would be commonly known in connection with such mechanisms. The stand is “collapsed” by the user pushing the outer nesting section 350 a and the base 352 towards each other. The stand is shown “open” in FIGS. 17 and 19 and “collapsed” or “closed” in FIGS. 18 and 20. FIGS. 21 and 22 depict the stand in both the “open” and “closed” positions.

The stand shown in FIGS. 23-26 is a tubular stand 810, shown with three base sections 811 a, 811 b and 811 c, three top sections 812 a, 812 b and 812 c and six support legs 814 a, 814 b, 814 c, 814 d, 814 e and 814 f. Stand 810 engages and supports the EFB bag during filling by having an excess amount of EFB bag material that is reversible on itself folded over the top sections 812 a, 812 b and 812 c.

Once the cut is made in a nozzle constructed in accordance with this invention, it remains possible to make a new cut, to enlarge the opening, without having to remove the food material from the bag and without having to take any other intermediary steps.

The design of the unique nozzle according to this invention allows the food material to be dispensed through the nozzle in a uniform, controlled and yet easy and effortless manner. Problems of lumps and clogs no longer cause the dispensation to have to be stopped to take time consuming remedial measures.

The dimensioning of the tip has been found to be critical. Slitted nozzle end designs of prior art devices may “give enough” to allow food to pass, but they are not capable of both widening out to enable desired passage of lumps and subsequently providing continued “treatment.” Moreover, slitted ends can result in ribbons of food coming out the side of the nozzle hole when a lump is encountered. Further, slitted ends preclude the selection of a cut area anywhere along the longitudinal length of the conical nozzle. The longitudinally extending internal protrusions of this invention overcome such deficiencies.

The material used to manufacture the nozzle is critical. It cannot be rigid as with prior art devices as it will not allow lumps or clogs to be passed. At the same time, it must not be too elastic so that the nozzle has no “integrity” and thus no control of the flow of the food material. A suitable elastic material in the embodiment where the nozzle is expected to flex and open would be either a thermoset elastomer, such as latex rubber or silicone rubber, or a thermoplastic elastomer, such as polyurethane. A suitable flexible but non-elastic material would be a thermoplastic such as polyethylene. These materials enable the user to clear clogs without taking the food out of the bag, either by expanding to allow the clog to pass (preferred), or by allowing the user to crush and break up the clog (alternative).

The nozzle should be made of a material of between 27 A and 60 A durometers, with 60A being the preferred embodiment.

In the preferred embodiment, the widest cut of the nozzle should yield a star shaped opening of up to 0.8 inches in inside diameter.

The cut lines can be notches as shown and can include colors and a color coded guide to help the user understand where to cut.

Referring to FIGS. 27 and 28, in order to introduce color into the food material as it is expelled, pre-positioned quantities of coloring agents can be manufactured into one or more reservoirs 710 a and 710 b in the bag 712 as shown in FIG. 27 or one or more reservoirs 710 c, 710 d and 710 e in the nozzle 714 as shown in FIG. 28, such that pressure (as well as heat and moisture) from the food material (not shown) can activate the reservoirs 710 a-e and cause the simultaneous expulsion of the coloring agents. If the reservoirs 710 a and 710 b are located in the bag 712 (FIG. 27), tubes or piping 716 a and 716 b can lead from the reservoirs 710 a and 710 b down alongside the edge of the nozzle 718 to a closed end at the area of the end of the nozzle 720. Cutting the nozzle can simultaneously result in cutting of the color tubes or piping 716 a and 716 b. If the reservoirs 710 c, 710 d and 710 e are located in the nozzle 714 (FIG. 28), tubes or piping 716 c, 716 d and 716 e (not shown) can lead from the reservoirs 710 c, 710 d and 710 e alongside the edge of the nozzle 714 to a closed end at the area of the end of the nozzle 720. Cutting the nozzle can simultaneously result in cutting of the color tubes or piping 716 c, 716 d and 716 e.

Referring to FIGS. 29 and 30, an alternate embodiment for introducing color into the food material as it is expelled is disclosed. Pre-positioned quantities of coloring agents can be placed in longitudinally extending deposits 740 a and 740 b on the internal surface 750 of the bag 752 as shown in FIG. 29 or placed in longitudinally extending deposits 740 c and 740 d on the internal surface 760 of the nozzle 762 as shown in FIG. 30. Prior to use, the integrity and viability of the color deposits, whether on the internal wall 750 of the bag 752, or on the internal wall 760 of the nozzle 762, is ensured by sealing strips 770 a, 770 b, 770 c and 770 d that overlay and seal the color deposits. Prior to depositing the food material in the bag 752, or prior to using the nozzle 762, in order to prepare the color deposits for “activation” by the passage of food material thereby, such sealing strips 770 a, 770 b, 770 c and 770 d are removed by pulling on tabs 772 a, 772 b, 772 c and 772 d, respectively. Alternatively, coloring agents such as food coloring gels can be inserted into the bag 752 and applied to the internal surface 750 of the bag 752 just prior to the time when the food material is inserted into the bag. For example, using a stick or any other transfer device, color gel can be taken from a gel pot and applied to the inside wall 750 or 32 of the bag 752 or 12, respectively. As another example, color gel can be squeezed out of a dispensing tube onto the inside wall 752 or 32. The sides of the bag 752 or 12 are then rubbed together to distribute the color around the entire outside of the bag. Alternatively, one color gel is applied to one area of the inside wall 750 or 32, and one or more other colors of gel are applied to one or more other areas of the inside wall 750 or 32 (for example, to achieve a multi-colored three dimensional ribbon candy appearance.

Referring to FIG. 31, food material 880 with a three dimensional ribbon candy appearance is shown being produced with the EFB apparatus of this invention. The food material 880 has channels 882 having peaks 884 and valleys 886, with a different color 888 on each of the channel peaks 884 than the color 890 in each of the channel valleys 886. The alternating stripes of color 888 and 890 on the peaks 884 and in the valleys 886 are produced by: (a) exposing the food material 880 to coloring agents 740 a and 740 b that were either: (i) applied to the internal surface or inside wall 750 of the bag 752 during manufacture of the bag (as seen in FIG. 29); or (ii) inserted into the bag 752 or 12 and applied to the inside wall 750 or internal wall 32 just prior to insertion of the food material into the bag; and then by (b) “treating” the food material 880 as it is expelled from the bag 752 or 12 through the orifice 762 or 10 by the protrusions, serrations or ridges 34 in the orifice.

More specifically, and as best seen in FIG. 31A, the food material 880 has the channel peaks 884 and the channel valleys 886 cut into it by the protrusions, serrations or ridges 34 as the food material passes through the orifice 762 or 10. First portions 892 of food material that were in contact with the coloring agents on the inside of the bag pass through the orifice 762 or 10 unobstructed and are expelled out on the peak 884 of each channel 882 with the effects of the coloring agents displayed. On the other hand, the longitudinally extending protrusions, serrations or ridges 34 in the orifice 762 or 10 cut into the food material 880 and expose second portions 894 of the food material that were not in contact with the coloring agents on the inside of the bag, which second portions 894 are expelled out in the valley 886 of each channel 882 without any effect of the coloring agents being displayed. The “treatment” of the food material which occurs within the apparatus of this invention is unique and not possible to replicate with prior art DDB apparatus.

FIGS. 31A and 31B are close-up perspective views of the EFB apparatus of this invention showing the “treatment” of the food material within the orifice that yields the unique three dimensional ribbon candy appearance in the expelled food material. The size of the opening cut into the orifice 762 or 10 of FIG. 31A is small whereas that size of the opening cut into the orifice 762 or 10 of FIG. 31B is much larger. Nevertheless the unique construction of the orifice 762 or 10 of this invention in both cases achieves the “treatment” of the food material within the orifice that yields the unique three dimensional ribbon candy appearance in the expelled food material.

FIG. 32 is a top plan view of a straight line of food material 880 expelled from the EFB apparatus of this invention with a three dimensional ribbon candy appearance. The channels 882 with peaks 884 and valleys 886 can be seen with alternating colors 888 and 890. This figure most clearly shows the unique “treatment” of food material that is only possible with the EFB apparatus of this invention and is much sought after in connection with decorating applications.

FIGS. 33 through 37 show various unique decorating designs that can be produced when food material 880 is “treated” with the EFB apparatus of this invention to yield a three dimensional ribbon candy appearance that is not possible with prior art DDB apparatus.

FIG. 33 shows a stream of food material produced with the EFB apparatus of this invention with a three dimensional ribbon candy appearance and, through the manipulation of the EFB apparatus during expulsion, a “braid” design 894. A first “piece” of material 894 a is expelled while moving the outlet of the orifice from one side to the other and then back to and ending in the “center”—all the while making an “S” shape curve design. Then a second “piece” of material 894 b is expelled with the same shape as the first, starting as if coming out of the side of the first, crossing over the “end” of the first and ending in the center in spaced relationship from the end of the first. Thereafter successive “pieces” of material 894 c (etc.) are similarly produced to create a “braid” design.

FIG. 34 shows a stream of food material produced with the EFB apparatus of this invention with a three dimensional ribbon candy appearance and, through the manipulation of the EFB apparatus during expulsion, a horizontally undulating “scallop” design 896 a (FIG. 31 shows a vertically undulating “scallop” design 896 b).

FIG. 35 shows a stream of food material produced with the EFB apparatus of this invention with a three dimensional ribbon candy design and, through the manipulation of the EFB apparatus during expulsion, having a vertically stacked “swirl” design 898 a.

FIG. 36 shows a stream of food material produced with the EFB apparatus of this invention with a three dimensional ribbon candy design and, through the manipulation of the EFB apparatus during expulsion, having a horizontally drawn out “swirl” design 898 b.

FIG. 37 shows a stream of food material produced with the EFB apparatus of this invention with a three dimensional ribbon candy design and, through the manipulation of the EFB apparatus during expulsion, having a “star” design 900.

As is readily apparent to anyone skilled in the art of decorating, many other designs with a ribbon candy appearance that were heretofore not possible with prior art DDB devices are now possible through the novel design of the EFB and manipulation of the EFB apparatus as the stream of food material produced with the EFB apparatus of this invention with a three dimensional ribbon candy appearance is expelled from the EFB apparatus. Although some embodiments have been described with respect to a plastic, disposable nozzle, note that any embodiments might instead be associated with other types of nozzles (e.g., a non-disposable metal nozzle or top). While the preferred embodiments of the invention have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made therein without departing from the spirit of the invention, the scope of which is defined by the appended claims.
